State and local officials gathered Wednesday for a ribbon-cutting ceremony for Cayce’s new $53 million regional wastewater treatment plant.

The plant, which took three years to build, has the capacity to treat 25 million gallons daily, roughly 2.5 times the capacity of the old plant, which was built in the 1970s. The new plant is capable of treating wastewater from 80,000 homes and businesses, and about 500,000 people.

The facility on Charleston Highway will provide long-term economic benefits to Lexington County by ensuring the continued availability of wastewater treatment capacity, the city said in a press release. It also is designed to protect the waters of the region from the by-products of this growth.

“This plant is the result of more than a decade of work, so standing here today is an exciting milestone for all of us,” Cayce Mayor Elise Partin said. “This is an excellent example of what can be accomplished with leadership and regional collaboration and we are excited that this new facility will help drive economic development in Lexington County.”

A number of new businesses have moved into the Cayce area in recent years including SCANA headquarters, an Amazon distribution center and Nephron’s new pharmaceutical plant.

Owned by the city of Cayce, the plant provides wastewater treatment to Cayce, the town of Lexington and the Joint Municipal Water and Sewer Commission, which serves the central and southern unincorporated areas of Lexington County.

The plant features a number of new purifying technologies including:

  • An advanced biological treatment process that’s capable of removing pollutants such as nitrogen and phosphorus from treated wastewater. A drop of water entering the plant takes one to two days to complete its journey through the facility.
  • An advanced membrane digestion system that eliminates the use of polymers, producing reuse-quality water and lowering the amount of nutrients released into waterways.
  • An automatic control system helps plant staff to monitor the treatment process and the equipment.
